Enable this option to debug the use of the DMA API by device drivers.
|
||||
With this option you will be able to detect common bugs in device
|
||||
drivers like double-freeing of DMA mappings or freeing mappings that
|
||||
were never allocated.
|
||||
This option causes a performance degredation. Use only if you want
|
||||
to debug device drivers. If unsure, say N.
